Can someone post the corresponding number values for the 200 and 170 scene files? Detail, V detail, chroma, pedestal etc. I am looking for the 170 values to correspond to HVX200 values at zero.

Yes,
I would also like to know... Meanwhile I'm doing my own experiment trying to get them has close has possible.

I order know know these you'd just need to know the adjustment offsets that are set-up via a tether cable and a MS-DOS pc program on both cameras at factory, rest should be quiet easy to compute.

However the HVX200(prior to A) and HPX170 have a different image sensor so matching between those could prove difficult just based on byte values alone in the sensor/codec boards.

I hate to say it, but the best would be to post it in something like Color, so long as it's with-in legal range a 4:2:2 should match up as well as it could.

I don't think it's "that" important as the two would be shooting a diffident picture so if you attach a scope to both for multicam you'd get a different reading anyway.

Obviously at 4:4:4 you would have a lot more room to do correction in the post.
